Supported device protocols

The SOMAC Communication Driver is designed to provide direct connectivity to the Schneider Electric controllers from the Modicon family. It uses TCP/IP (Transmission Control Protocol/Internet Protocol) bus-level protocol to communicate with all devices across an Ethernet network.

TCP is the lower-level transport and data-link vehicle for data delivery over an IP network. It provides reliable connection-oriented full-duplex data stream transport. IP is the basic protocol for the Internet which uses an IP address scheme to send data in packets across networks.
